Thank to a bacteria, sand is solidified into a habitable structure that protects from wind and sand. As the architect Magnus Larsson said: "in this way, we can start 'growing' controlled oases in the desert, and stop the sand from pushing people away from their homes and villages, which, in the worst-case scenario, may lead to huge migration floods, food shortages, wars, and other horrible situations". Starting upon a research carried out by professor Jason De Jong's team at the Soil Interactions Laboratory, UC Davis (http://www.sil.ucdavis.edu/people-jason.htm), as well as conversations with professor Stefano Ciurli at the University of Bologna, Larsson designs to flush a particular microorganism, Bacillus Pasteurii, through the dunescape to cause a biological reaction that turns the sand into solid sandstone.
